Performance indicators in Rugby Union

Hughes MT, Hughes MD, Williams J, James N, Vuckovic G, Locke D. Performance indicators in rugby union. J. Hum. Sport Exerc. Vol. 7, No. 7, pp. 383-401, 2012. Team performance in rugby has typically been assessed through the comparison of winning and losing teams, however, the distinction between winning and losing was used as the sole independent variable. Thus potential confounding variables that may affect performance such as match venue, weather conditions and the strength of the opposition were not considered in this profile of a rugby team. Insufficient data currently exist regarding the development and measurement of performance indicators in rugby union. In particular, there is little research concerning position-specific performance indicators and their subsequent performance profiles. Research has also yet to establish the confidence to which these performance profiles are representative of an individual’s performance. The aim of this study was to exploit the unique opportunity of a large dataset from the 2011 World Cup, from analysts working with national teams, and combine this with examples of data taken from previous studies, in an attempt to identify a more focused direction for the analysis of rugby union. The majority of data collected in the results section were during and after the 2011 Ruby Union World Cup in New Zealand by professional analysts working for a firm called PGIR, which has the analysis franchise for the England RFU. All data were checked for accuracy and reliability by cross-referencing actions to post event from video. It was concluded that in a complex dynamic interactive team sport, such as rugby, that simple analyses of frequency data, although informative, cannot possibly be expected to model this very difficult and multivariate problem. Key words: PERFORMANCE INDICATORS, RUGBY UNION

休斯MT，休斯MD，威廉姆斯J，詹姆斯N，武科维奇G，洛克D。英式橄榄球的表现指标。《人类运动与锻炼杂志》，2012年第7卷第7期，第383 - 401页。英式橄榄球的团队表现通常是通过对胜队和败队的比较来评估的，然而，胜负之间的区别被用作唯一的自变量。因此，在对一支橄榄球队的这种描述中，没有考虑可能影响表现的潜在混杂变量，比如比赛场地、天气状况以及对手的实力。目前关于英式橄榄球表现指标的制定和测量的数据不足。特别是，关于特定位置的表现指标及其后续表现情况的研究很少。研究也尚未确定这些表现情况在多大程度上能代表个人表现的可信度。本研究的目的是利用2011年世界杯的一个大型数据集所带来的独特机会（这些数据来自为国家队工作的分析人员），并将其与从以往研究中获取的数据实例相结合，试图为英式橄榄球的分析确定一个更有针对性的方向。结果部分收集的大多数数据是由一家名为PGIR的公司的专业分析人员在2011年新西兰英式橄榄球世界杯期间及之后收集的，该公司拥有英格兰橄榄球联合会的分析特许权。通过将动作与视频中的赛后情况进行交叉参照，对所有数据的准确性和可靠性进行了检查。结论是，在像英式橄榄球这样复杂的动态互动团队运动中，对频率数据的简单分析虽然能提供信息，但不可能期望以此来模拟这个非常困难且多变量的问题。关键词：表现指标，英式橄榄球
